Detailed analysis
Context Length
Winner: Grok 4.20 Multi-AgentGrok 4.20 Multi-Agent supports a 2M token context window compared to GPT-5.4 Pro's 1.05M tokens. This gives Grok a clear advantage for massive context multimodal tasks involving extensive text, images, and files.
Pricing
Winner: Grok 4.20 Multi-AgentGrok 4.20 Multi-Agent is priced at $2.5 per million output tokens while GPT-5.4 Pro costs $180 per million. The substantial price difference favors Grok for high-volume or budget-conscious multimodal usage.
Workflow & Reasoning
Winner: TieGrok 4.20 Multi-Agent offers multi-agent coordination for workflows alongside native multimodal support. GPT-5.4 Pro provides advanced reasoning over extended contexts with strong text-image-file integration, suiting different task styles without a clear overall winner from the given facts.
Modality Support
Winner: TieBoth models handle text, images, and files natively but lack audio or video support. Grok emphasizes multi-agent handling while GPT-5.4 Pro focuses on integrated reasoning, resulting in equivalent core modality coverage.
GPT-5.4 Pro
Pros
- +Handles very large inputs across modalities
- +Strong integration of text, image, and file data
- +Advanced reasoning over extended contexts
Cons
- –Higher latency on maximum-length inputs
- –No native audio or video support
- –Proprietary access with usage constraints
Grok 4.20 Multi-Agent
Pros
- +Supports extremely long contexts
- +Coordinates multiple agents for workflows
- +Handles text, images, and files natively
Cons
- –Multi-agent setups may add latency
- –Coordination overhead on simple tasks
- –No audio or video modalities
Summary: GPT-5.4 Pro vs Grok 4.20 Multi-Agent
Select Grok 4.20 Multi-Agent for maximum context, multi-agent workflows, and low cost on large-scale multimodal projects. Choose GPT-5.4 Pro when advanced reasoning integration within a large but smaller context window is the priority. Both remain comparable on basic multimodal capabilities excluding audio and video.
